    RM1233A Features:
    Working voltage 2.3V~5.5V
    The built-in voltage regulator circuit provides stable voltage for the detection circuit to use
    Built in Low Voltage Reset (LVR) function
    Working current 6ua@vdd =3V, no load
    Low power standby current 2ua@vdd =3V, no load
    Flexibly adjustable sensitivity, no external capacitance required, maximum parasitic capacitance value of 30pF
    Touch detection input pins connected in series with a 0-100K resistor can adjust sensitivity
    The output mode has been configured, eliminating the need for external selection resistors
    Optional CMOS output/open drain output, effective for high/low levels
    The touch output pin provides a maximum output time of 16 seconds
    After power on, there is a stable time of about 0.5 seconds
    Automatic calibration function, environmental adaptive calibration function
    DFN-6L, SOT23-6L packaging

    RM1233A Application:
    Various consumer products
    Replace button buttons
